Questions 2

What is the result if force encryption for media is enabled in the Expressway on a zone that points to a system/endpoint that is not configured for encryption?

Options:
A.

The call is dropped.

B.

The call works with one end only sending encrypted media.

C.

The call renegotiates for unencrypted media.

D.

The call uses encryption if available, or it falls back to unencrypted media.

Questions 3

Options:
A.

Expressway Control is the traversal server installed in the DMZ.

B.

The Expressway Edge must be put in a firewall DMZ segment.

C.

Cisco Unified Communications Manager zone can be either traversal server or client.

D.

The Unified Communications traversal zone can be used for Mobile and Remote Access.

E.

Both Expressway Edge interfaces can be NATed.

Questions 4

A call is sent by Cisco UCM to Expressway with a URI of 75080001@expc1a.pod8.test.lab. If (7508…)

@expc1a\.pod8\.test\.lab.* is the pattern string, what would be the replacement string of the transform in Expressway to re-write the call so that it becomes 75080001@conf.pod8.test.lab?

Options:
A.

\1@conf\.pod8.test.lab.@

B.

\1@conf\.pod8\.test\lab.*

C.

\1@conf.pod8\.test\.lab

D.

Questions 5

Refer to the exhibit.

300-820 Question 5

Calls to locally registered endpoints are failing. At present, there are two endpoints

registered locally to this Expressway. An H.323 endpoint with an alias of “EndpointA” is registered, and a SIP endpoint with an alias of “EndpointB@pod1.local” is also registered. How is this issue resolved?

Options:
A.

The dialplan must be redesigned to use the transforms to convert the alias into SIP URI format and then use separate search rules for each format that needs to be dialed within the local zone.

B.

The calls are failing because there are insufficient licenses. Additional licenses must be installed for the Expressway to route these calls.

C.

The current search rule does not match the call, so the search rule must be modified to include a SIP Variant of “Standards-Based”.

D.

Calling parties are placing calls with the wrong domain. End-users must be instructed not to use the

pod1.local domain as that is owned by the local system. Calls to any other domain would work.
